[ubuntu-mono] [Bug 1008212] [NEW] x11 dllmap points to unversioned library

[Julian Taylor]

Public bug reported:

/etc/mono/config contains the dllmap for libX11 but it points to the .so
 <dllmap dll="libX11" target="libX11.so" os="!windows" />

the .so is only included in libx11-dev.
it should point to the versioned .so.6 contained in libx116

TEST CASE:
compile this with dmcs:

$ cat libx11.cs
using System;
using System.Runtime.InteropServices;
class X11Test
{
    [DllImport ("libX11")]
    static extern void XAllPlanes ();
    static void Main(string[] args)
    {
      XAllPlanes ();
    }

}

$ dmcs libx11.cs
$ ./libx11.exe

Unhandled Exception: System.DllNotFoundException: libX11.so
  at (wrapper managed-to-native) X11Test:XAllPlanes ()
  at X11Test.Main (System.String[] args) [0x00000] in <filename unknown>:0
[ERROR] FATAL UNHANDLED EXCEPTION: System.DllNotFoundException: libX11.so
  at (wrapper managed-to-native) X11Test:XAllPlanes ()
  at X11Test.Main (System.String[] args) [0x00000] in <filename unknown>:0

expected:
no backtrace

FIX: this is caused by the build not finding the multiarched library
it was fixed in -4:
   [ Jo Shields ]
   * [f77ef2f] Tweak build system to check multiarch library folder for
     libX11.so.
